Asset and reporting data carried through S/4HANA with zero blackout

A representative engagement. The risk that scared leadership was losing reporting, not the ERP conversion itself. We modernized BW and protected continuity through cutover.

Challenge

A roughly 2,800-person energy and utilities company on SAP ECC ran operations off a sprawling BW estate built over a decade, with hundreds of objects, many unused, and extractors that would break against S/4HANA. Asset and equipment master data was inconsistent across systems. If reporting went dark during the migration, operations and compliance reporting would both suffer.

Approach

We combined a Blueprint and Readiness Assessment with BW modernization. We inventoried the estate, measured what was actually used, and retired the dead weight. We mapped every reporting dependency, re-pointed the extractors and models that mattered to the new S/4HANA structures, and validated reports reconciled to source. In parallel we cleansed and reconciled asset and equipment master data, and positioned the surviving estate for a future Datasphere foundation.

Outcome

Reporting continued through the migration with no blackout. The estate was far smaller and easier to run, the numbers reconciled to the migrated data, and the company had a defined route to modern analytics rather than a like-for-like lift.

Rationalize, do not lift

Most of the estate was unused. We measured real usage and retired the dead weight, so the company carried forward only what mattered instead of copying a decade of clutter into the new system.

Re-point and validate

We adapted the extractors and models that mattered to the new S/4HANA structures and validated that reports reconciled to source, so reporting kept working through the move.

A path to modern analytics

We positioned the surviving estate for a governed Datasphere foundation, so the migration became the moment analytics moved forward rather than a setback.

Results

  • 16 wks Assessment, remediation, and BW modernization
  • 2,100 to 680 BW objects, before and after rationalization
  • Zero Reporting blackout days through the migration
  • $1.3M Cost of a like-for-like BW lift avoided

Our biggest fear was going blind on operational reporting during cutover. It never happened. Thinklytics planned reporting continuity as part of the migration, retired years of clutter, and left us a foundation we can build on.

The question

What stops reconciling the day we cut over?

The situation

An energy and utilities company of around 2,800 people ran operations off a BW estate built over a decade: hundreds of objects, many unused, and extractors that would break against S/4HANA. Asset and equipment master data was inconsistent across systems. A reporting blackout would have hit operations and compliance together.

What we found

Most of the estate was not load-bearing. The default plan was a like-for-like lift, which would have carried a decade of dead objects into the new platform at full cost and left the same problem to solve later.

What it produced

Reporting ran through the migration with zero blackout days. BW objects fell from 2,100 to 680, leaving an estate that is materially cheaper to run. The numbers reconciled to the migrated data, and the cost of a like-for-like lift, $1.3M, was avoided.

The roadmap

Assessment was combined with BW modernisation rather than sequenced after it. The estate was inventoried and measured by actual use, and the dead weight was retired before anything moved. Every reporting dependency was mapped, the extractors and models that mattered were re-pointed at the new S/4HANA structures, and reports were validated by reconciling to source. Asset and equipment master data was cleansed in parallel, and the surviving estate was positioned for a Datasphere foundation.

Frequently asked questions

Should you migrate a BW estate as-is to S/4HANA?

Rarely. This energy company's default plan was a like-for-like lift of a decade of objects, most unused. Measuring actual usage first took the estate from 2,100 objects to 680 and avoided $1.3M for carrying clutter into the new platform.

How do you keep BW reporting running through an S/4HANA migration?

Map every reporting dependency, re-point the extractors and models that matter to the new structures, and validate by reconciling reports to source. This migration ran with zero reporting blackout days.

What happens to BW after S/4HANA?

It can be the moment analytics moves forward rather than sideways. The surviving estate here was positioned for a governed Datasphere foundation rather than rebuilt as it was.
